About Breath-O Correct

Good to know

Indicated for overnight wear for myopia and myopic astigmatism
At least 5 hours of overnight wear are recommended
Specially designed for Asian corneas, which tend to be flatter
Prescribed and fitted by an eye care professional, with regular examinations

Design and material

Principle of orthokeratology. Corneal topography is reshaped by direct wear of the contact Lens on the anterior segment of the eye. After removal, unaided vision is improved.

Before insertion, while sleeping and after removal.
Designed for Asian corneas. Corneas of Asian people tend to be relatively flatter than those of Western people. Breath-O Correct is specially designed for Asian people whose corneas are flatter: a shallower sagittal depth makes a wider optical zone.
Lens structure. From the edge inwards, a peripheral curve, fitting curve and reverse curve surround the BCOZ of 6.2 mm, across a Lens diameter of 10.2 to 11.0 mm.

Oxygen supply to the cornea. Breath-O Correct's material has an oxygen transmissibility (Dk/t) of 78 and an oxygen permeability (Dk) of 156.
High durability. The flexible material is based on Toray's original polymer technology. The components retain strength and the Lens bends flexibly in response to impacts from outside to prevent cracking.
